Hi,
Change #1 sounds easy - I will modify the reg page to include this new field and I will make the php script save that information in you database as well.
#2 - Can you provide me with developer documentation on integrating this one? Or if there is none I can also see how it worked on your wordpress site and then adjust it to this registration page.
#3 - this sounds like it needs the characters encoding changed to Unicode, which will support virtually any character.
#4 - I can integrate a recaptcha field, which will ask the user to fill in 2 words from the image before submitting. This will be more than enough to stop spammers!
I am a software engineering student with a back track of successful projects on here, as well as 1 year of industrial experience as a PHP web developer for a small IT company - Gloversure Ltd, based in Welshpool UK.
Please do not hesitate to contact me and discuss this further!
Regards,
Boris
